| .B #include <libc.h> |
| .sp |
| .B |
| char* cleanname(char *filename) |
| .SH DESCRIPTION |
| .I Cleanname |
| takes a |
| .I filename |
| and by lexical processing only returns the shortest string that names the same (possibly |
| hypothetical) file. |
| It eliminates multiple and trailing slashes, and it lexically interprets |
| .B . |
| and |
| .B .. |
| directory components in the name. |
| The string is overwritten in place. |
| .PP |
| The shortest string |
| .I cleanname |
| can return is two bytes: the null-terminated string |
| \f(CW"."\f1. |
| Therefore |
| .I filename |
| must contain room for at least two bytes. |
